Summary
This study tested whether inhaling special tracer gases (xenon and perfluoropropane) can improve MRI images of the lungs. It involved 24 healthy volunteers aged 6 to 75. The goal was to develop better imaging hardware and software, not to treat any disease. The study was terminated early.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Inhaled tracer gases (hyperpolarized xenon and perfluoropropane)
What this could lead to
If successful, this could lead to better, non-invasive lung imaging techniques that don't use radiation.
What could go wrong
The study was terminated early and only included healthy volunteers, so results may not apply to people with lung disease. The technology is still in early development.
As listed by the trial registrant
The condition terms exactly as the trial's registrant entered them.
